Webhooks

Webhooks are a widely supported method used to allow multiple applications to interact with each other, using HTTP POST requests to pass callbacks between them. For more information, see Wikipedia's page on webhooks. Common uses for webhooks include sending notifications via email or SMS, posting messages to social media, automatically writing records to a spreadsheet, and updating enterprise databases.

Starting with Survey123 for ArcGIS 3.0, webhooks can be set up and activated when a survey response is submitted. For example, after a successful submission of information to the feature layer, the webhook could be called and trigger another action, such as sending a notification email, appending the survey content to a spreadsheet, and sending an alert.

Your workplace may have its own webhook provider, but a wide variety of third-party workflow services are available, such as Integromat, Microsoft Flow, Zapier, and tray.io. All of these can be used to incorporate Survey123 as a trigger for a greater automated process. In particular, Integromat and Microsoft Flow have a Survey123 connector, allowing you to integrate Survey123 into your webhook workflow with minimum difficulty, and without the need to configure the webhook in the Survey123 website or to input a payload URL.

The following sections demonstrate how to set up a notification webhook to send an email when a response has been sent that contains a question answered with a certain value.

There are endless ways you can use Survey123 as a trigger in your workflows. To get started, Integromat has templates that you can use to include attachments in your email notifications, add records to spreadsheets, and create calendar items.

Note:

If the survey you apply a webhook to has already been downloaded in the Survey123 field app, it will need to be downloaded again for the webhook to work.
